You say messy, i say part of the Art.
I love it. everything is greatly done, and i feel the "messy lines" in a way, fit the look. Only reason i gave it a 9 is simply out of personal opinion; the "i got soul" text felt out of place, and i wish the background had detail. they felt rushed into place for filler, which is alright.
Note: Those issues don't fully reflect your talent of digital art and drawing, so 10/10 based purely on the woman and her beautiful hair :P.
